Lessee Accounting under ASC 842 / IFRS 16 with SAP CLM

ASC 842 and IFRS 16 changed lessee accounting fundamentally. Almost all leases now appear on the balance sheet as a right-of-use asset and a lease liability. For companies with hundreds or thousands of lease contracts, this requires a system that can capture contracts, calculate values, and generate postings reliably. SAP Contract and Lease Management (CLM) is SAP's solution for this within SAP S/4HANA.

The Lessee Model: ASC 842 vs. IFRS 16

Both standards require lessees to recognize a right-of-use asset and a lease liability for most leases. The main difference is in the income statement:

• IFRS 16 uses a single lessee model. All leases are treated like financing, similar to ASC 842 finance leases: depreciation of the right-of-use asset and interest on the lease liability.

• ASC 842 distinguishes between finance leases and operating leases. Finance leases are treated like financing: amortization of the right-of-use asset and interest on the lease liability. For operating leases, a single, generally straight-line lease cost is recognized.

Both standards offer exemptions, for example for short-term leases. IFRS 16 also offers an exemption for leases of low-value assets.

Key Steps in Lessee Accounting

1. Identify the Lease

Determine whether a contract contains a lease: Is there an identified asset, and does the company control its use?

2. Determine the Lease Term

Include periods covered by extension options that are reasonably certain to be exercised, and termination options that are reasonably certain not to be exercised.

3. Determine Lease Payments

Fixed payments, variable payments based on an index or rate, expected residual value guarantees, and purchase options that are reasonably certain to be exercised.

4. Determine the Discount Rate

Use the rate implicit in the lease if readily determinable; otherwise, the lessee's incremental borrowing rate. ASC 842 also offers a risk-free rate option for certain entities.

5. Measure Initially

Calculate the lease liability as the present value of lease payments and the right-of-use asset based on the liability, adjusted for initial direct costs, prepayments, and incentives.

6. Measure Subsequently

Recognize interest, reduce the liability with payments, depreciate the right-of-use asset (or, for ASC 842 operating leases, recognize straight-line lease cost).

7. Remeasure When Required

Changes in lease term, payments, or index-based amounts lead to remeasurement.

How SAP CLM Supports the Process

Contract capture

Lease contracts are stored centrally with their terms, conditions, options, and payment schedules.

Valuation rules

CLM applies valuation rules per accounting principle, including discount rates, exemptions, and the classification required under ASC 842.

Calculation and schedules

Lease liabilities, right-of-use assets, interest, and depreciation are calculated automatically, and schedules are generated over the lease term.

Postings

Initial recognition, periodic postings, and payments are integrated with the general ledger, asset accounting, and accounts payable.

Remeasurement

Contract changes trigger a recalculation, and the resulting adjustments are posted.

Parallel valuation

The same contract can be valued under ASC 842 and IFRS 16 at the same time.

Disclosures

CLM provides the data needed for lease disclosures, such as maturity analyses and expense components.

Common Challenges

• Data collection: Lease contracts are often spread across departments, and key data – options, payment escalations, incentives – is not available in a structured form.

• Embedded leases: Leases hidden in service contracts are easily overlooked.

• Discount rates: Determining incremental borrowing rates by term, currency, and entity requires a defined process.

• Modifications: Frequent changes require clear processes between the business and accounting.

• Volume: Large portfolios require efficient processes for contract maintenance and period-end.

The Bottom Line

Lessee accounting under ASC 842 and IFRS 16 is a data-intensive process. SAP CLM provides the functionality to capture, value, and post leases within SAP S/4HANA. Success depends on complete contract data, clear accounting policies, and well-defined processes for changes and period-end.
